Abstract
Abstract A system for transmitting, storing and utilizing cold which includes the use of heat pipes for transmitting the winter cold to cool the anti-freezing liquid in the ground cold storage which in turn freeze the water bags installed in the cold storage. When the complete air-conditioning system in a cooling environment is in operation, the coolant in the cold storage will be circulated through a bank of tubes situated inside the air-conditioning duct for cooling air as required. The system provides for long-duration earth storage of winter cold which can be effectively used during warm seasons for space cooling and cold storage.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A system for extracting, transmitting, storing, recovering and utilizing cold, said system comprising: a. apparatus for extracting cold from the environment; b. transmitting means comprising a heat pipe for transmitting said cold from environment above the ground to a location below the surface of the ground; c. storage means for storing cold including containers of freezable liquid submerged in liquid coolant, said containers and liquid coolant being located at said location below the surface of the ground for receiving and storing cold transmitted thereto by said transmitting means; d. recovery means for recovering cold from said storage means and delivering it to a second environment; and e. utilizing means connected to said recovery means for receiving cold therefrom and dispersing said cold throughout said second environment.
Claim 2
Independent Claim
126 words
A system for extracting, transmitting, storing, recovering and utilizing cold, said system comprising: a. apparatus for extracting cold from the environment; b. transmitting means comprising a heat pipe for transmitting said cold from environment above the ground to a location below the surface of the ground; c. storage means for storing cold including containers of freezable liquid submerged in liquid coolant, said containers and liquid coolant being located at said location below the surface of the ground for receiving and storing cold transmitted thereto by said transmitting means; d. recovery means for recovering cold from said storage means and delivering it to a second environment; and e. utilizing means connected to said recovery means for receiving cold therefrom and dispersing said cold throughout said second environment.
Claim 3
Dependent Claim
29 words
A system as defined in claim 1 wherein said storage means includes a plastic liner for containing said liquid coolant at said location below the surface of the ground.
Claim 4
Dependent Claim
25 words
A system as defined in claim 1 wherein said freezable liquid is water which changes phase to ice upon being cooled by said liquid coolant.
Claim 5
Dependent Claim
28 words
A system as defined in claim 2 wherein said liquid coolant is a substance which is capable of maintaining liquid state upon being cooled by said transmitting means.
Claim 6
Dependent Claim
24 words
A system as defined in claim 2 including insulation means located about said plastic liner for minimizing loss of cold to the surrounding earth.
Claim 7
Dependent Claim
33 words
A system as defined in claim 1 wherein said utilizing means includes a bank of flow tube means and means for passing relatively warm air across said flow tube for cooling said air.
Claim 8
Dependent Claim
79 words
A system as defined in claim 6 wherein said recovery means includes a closed-circuit pipe means having a first portion thereof connected to said storage means at said location below the ground, a second portion thereof extending from said location to said bank of flow tube means for delivering liquid coolant thereto, and a third portion extending from said flow tube back to said first portion for delivering said liquid coolant from said flow tube to said first portion.
Claim 9
Dependent Claim
36 words
A system as defined in claim 7 including pump means located in said second portion of said closed-circuit pipe means for pumping said liquid coolant through said second portion to said bank of flow tubes means.
Claim 10
Dependent Claim
48 words
A system as defined in claim 6 wherein said bank of flow tube means includes a manifold and a plurality of flow tubes connected to said manifold; and said recovery means including pump means for pumping said liquid coolant from said location below the ground to said manifold.
Claim 11
Dependent Claim
43 words
A system as defined in claim 7 including valve means located in said second portion of said closed-circuit pipe means for controlling said liquid coolant flow through said second portion to said first portion without passing through said bank of flow tube means.
Claim 12
Dependent Claim
15 words
A system as defined in claim 1 wherein said container resembles an inflated plastic bag.
Claim 13
Dependent Claim
23 words
A system as defined in claim 1 wherein said container includes at least one filling tube for exchanging of substance in said container.
